Problems And Difficulties Faced By Pneumatic Conveying Systems in The Food Industry
Food safety has received more and more attention from all walks of life, and higher requirements have been placed on food production equipment. There are many types of powdered raw materials in food factories. Such as flour, rice flour, corn flour, powdered sugar, starch, malt, etc. Many food companies are still stuck in the production mode of artificial ingredients and feed. It is easy to cause dust to fly and pollute the environment. Insects are prone to breed in the workshop, causing food safety problems. Workers have high labor intensity and many human factors, which make it difficult to control product quality.
Our pneumatic conveying system for the food industry solves the following problems and difficulties:
1. Equipment hygiene
Food machinery has very high hygiene requirements for the equipment itself, at least it must be clean, non-toxic, harmless, non-odor, non-polluting, and non-absorption.
1) The material in contact with equipment and materials is 304 stainless steel or above
2) The assembler should strictly follow the operating procedures
3) After the assembly is completed, immediately pack it, and do not expose it to the air for a long time
2. Conveying residue
If there are residues in the food machinery, it may cause the food to deteriorate. Therefore, in the design of the equipment, residues should be avoided as much as possible. When it is unavoidable, it should be easy to clean.
1) The contact surface between the equipment and the material should be a mirror surface
2) There should be no defects such as pits, creases, fractures, cracks, etc.
3 easy to clean
1) Food machinery cannot avoid the need for cleaning, so the design of pneumatic conveying equipment requires miniaturization, integration, centralization, rapid disassembly and rapid installation. All parts should be washable.
2) The inside of the pipe is mirrored, and the pipes are connected by quick joints, which are not easy to produce residues and are easy to disassemble and clean.
